We are looking for a sediment backwash filter to remove very fine sand from our well water system. Our flow rate is up to 50 gpm. We currently have a LAKOS Centrifugal Separator installed but it does not do the job. Any suggestions?"
Hello - It is not a bad idea to keep your Lakos separator but for very fine sand, a finer screen filter is necessary. After your Lakos separator, and after the pressure tank, you could install a flushable filter screen with 60 mesh.
A 2" size would be good to use, to have the larger screen and sump:
These filter screens are also called ‘spin down filters” and can be cleaned by opening up a valve on the filter and giving it a flush 10 – 20 seconds. These units also can be ordered with an optional auto-flush valve that make the flushing automatic.
If there is very fine silt or particles smaller than fine sand, we also have Sediment Backwash filters that filter to 5 microns:
